POURING-SPQUT.

Application filed June 5, 1919.

To all whom it may concern:

Be it 'known that I, HERMAN L. STRONG- SON, a citizenof the United States, and a resident of Springfield, county of Hampden, and State of Massachusetts, have invented a new and Improved Pouring-Spout, of which the following is a full, clear, and exact description.

This invention relates to pouring spouts. More particularly the invention discloses a device which may be applied to a sealed tin, or applied to any form of can which contains liquids to be decanted for the pur-.

pose of pouring the liquid from the can through a specially prepared spout, and kept covered by a closure cap.

An object of the invention is to provide a pouring spout fitted with a puncturing or cutting blade so that the pouring spout may be quickly inserted in the can and securely clamped thereto. It is a purpose of the invention to provide a pouring spout which will be sanitary in use and which will be closed at all times when the liquid is not being poured.

A particular object of the invention is to provide a pouring spout fitted with a puncturing blade, the design of which is so arranged as to tightly clamp the pouring spout against the to Figure 1 shows the pouring spout fixed to a can tilted up in service or pouring position.

Fig. 2 shows a vertical sectional view taken through the pouring spout with the plane of the section taken parallel with the plane of the puncturing blade.

Fig. 3 shows a vertical sectional view taken through the pouring spout tube, the section plane taken right angularly w th the plane of the puncturlng blade, with said blade removed. I

Fig. 4 shows a detailed view of a certain puncturing blade employed in connection with the tubular pouring spout.

of the can so as to form a liquid-tight oint between the can Patented Oct. 5, 1920. Serial No. 301,905.

closure, I employ a tubular member fitted with a puncturing blade, and provide means for securing a positive liquid-tight joint between the can and the pouring spout. The device is applied to the can and permanently left thereon during the period of use of the contents of the can.

In the drawings, a tubular member is shown which comprises an approximately round bottom end and flange 5. This round end is provided with shoulder portions 6 formed by cutting upwardly from the face of the flange. Slots 7 are cut in the wall of the tubular member adjacent the shoulder 6. The upper portion of the pouring spout is designated by the numeral 8 and is flattened so as to be approximately recthe pouring spout is provided with a shoulder 9 formed on each side of the tubular member. The shoulders 9 are formed upon an upper fiat portion of the tube while the shoulder 6 is of cylindrical form and cut in .the lower round portion of said tube. The tubular member is provided with a small indenture, drilled cavity or cast cavity 10 formed in the upper corner of said tube above the shoulders 9 and within each side Wall of the tubular member.

A puncturing blade 12 formed with a cross bar 13. This cross bar 13 isenlarged on each end as designated by 14. The enlarged portions 14 thus form shoulders 15 so as to provide a substantially narrow bar member 13 with substantially wide ears or broad portions 14. This cutting blade has downwardly inclined cutting edges 16 which converge to a point and thus form a sharp tapered cutting'member. The cutting edges 16 are terminated by the upwardly inclined clamping edges 17. The edges 17 are formed on an angle so as to join the bar 13 at an angle. The function of the upwardly inclined clamping edges 17 will appear as the description proceeds. The blade 12 is assembled with the tubular member by fitting the ears 14 thereof into the oppositely disposed slots 7. The blade bar is pressed into the slots and retained therein by inherent friction or made secure by riveting over the metal forming the slots X so as to lock the bar-therein, The broad is integrally per end of the pouring spout when the deby the tubular member and thrust through fitted within the slots so that the puncturing blade can not be turned or loosened .therein. The shoulders 15 forming the projecting ears thus space the underneath edge of the bar somewhat above the face of the flange. This construction disposes the puncturing blade 12 centrally within the round lower end of the tubular member, and thus leaves the tubular member open and unobstructed so as to admit the flow of liquids past the puncturing blade into the tubular member.

A gasket 18 of any appropriate material 'such as pliable andyieldable rubber is inserted in the bore forming the shoulder 6. This gasket will be pressed into the bore so that its walls will expansively engage the shoulder to retain it in position. Shelvice is not in service. This cover comprises a flat sheet metal member provided with integrally down-turned parallel 'sides 20 formed from the. top plate portion 21. The

upper plate portion 21 projects beyond the sides forming trip or finger pieces 22. The cover side pieces 21 are punched or indented at 24:. This punched-in portion 2 1 is provided upon each side piece 20 and registers withthe indented cavity 10. This hinges the cover member on the upper portion of the tube and effectually closes that tube. The lower edges of the side pieces 20 lay in engagement with,the shoulders 9. This construction forms an exterior smooth and flush finish between the surface of the cover and the surface of "the flat portion of the tubular member. Thefinger pieces 22 project just sufliciently to admit of the users fingers engag ng said projections for the purpose of .hingin the cover about its pivotal point 10. Either front or rear finger portions may be used. It may be preferable to form the cover cap even or flush on the front end and provide the rear end thereof with the finger trip 22 so that slight pressure thereupon will tilt'the cover aboutthe pivotal point 10 for opening the tubular member.

In use, this pouring spout will be grasped the center of a milk tin or other sealed container so that the blade 12-punctures the top thereof and brings the gasket 18 into compressive engagement with the outer surface of said can. The upper flat portion of the tubular member may be grasped between the thumb and forefinger of the person and the whole device given a onequarter turn. The upper flattened portion of the tubular member renders it easy and v This exerts a downwardly against the surface of the can when the punctured tin edges 25 creep downwardly along the inclined edges 17 thus compressively engaging the gasket 18 against the surface of the can. The edges 25 curl downwardly along the edge 17'and eifectuates the clamping action. The device is especially designed to leave sufficient space between the surface of the can and the adjacent edge of the bar so as to leave room to draw the blade and bar downwardly without contacting the can surface. This function is illustrated in Fig. 2.

This pouring spout may be left in position upon the can as long as the contents are to be used and will thus provide an adequate pouring means 7 for decanting the liquids therefrom, and further provide a positively sealed can when the cover plate is in downwardly closed position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:

1. A pouring spout for cans, comprising a tubular member, said member having a recess formed in one end thereof, a bar anchored in the tubular member back of the from the bar which coacts with the gasket to clamp the pouring spout on a can.

2. A pouring spout for cans, comprising a tubular member, said member having a recess formed in one end thereof, a bar anchored in the tubular member back of the recess, and a blade fixed to and extending from the bar. a a I 3. A pouring spout for cans, comprislng a tube flattened at one end to provide a convenient hand grip,'a recessed flange formed on the other end of the tube, a gasket fitted into the recess, a bar anchored in the tube back of the recess and gasket, a spear shaped blade fixed to and extending from the bar and coacting with the gasket to clamp the spout on a can and form a fluid tight joint; I

between the pouring-spout and can.
